BGE: How to display random list of text in game with python?
ah this is a simple python problem.

if I understand correctly all you have to do is

import random
print(random.randint(0,len(tips)-1))


or

import random
random.choice(tips)


of course actually displaying them in the game itself is possible, just slightly more complicated.

also next time please post a python question in a python thread.
